Connect your on-premises data center (IDC) to an Alibaba Cloud Express Connect access point through a partner, who provisions a hosted connection for you.
Prerequisites
The partner has completed the required preparations.
For a new hosted connection, the partner has created a shared port for you.
For an existing cross-account VBR instance, the partner has converted the connection to use a shared port.
You are familiar with the billing rules for hosted connections.

Convert an existing cross-account VBR instance to use a shared port |

Step 1: Accept a shared port
After the partner notifies you, accept the shared port in the Express Connect console and pay the resource usage fee. This applies to both new hosted connections and conversions of existing cross-account VBR instances.
If the partner has already paid the resource usage fee for you, you only need to accept the shared port and do not need to make a payment.
Log on to the Express Connect console.
In the top navigation bar, select the target region.
On the Physical Connection page, find the target shared physical connection instance, and then click Accept and Pay in the Actions column.
In the Accept dialog box, click OK.
In the panel that appears, confirm the region, specifications, and other information about the shared port. Then, click Buy Now and complete the payment.
After the payment is complete, the Status of the shared physical connection changes to Active, and the Construction Procedure changes to Complete.
NoteAfter you accept the shared port that the partner converted, the partner must confirm the conversion to complete the process. After the conversion, the existing VBR instance is associated with the converted shared port. The configuration of the VBR instance remains unchanged and your services are not affected during this process.
Step 2: Create a VBR instance
Create a Virtual Border Router (VBR) instance on an accepted shared port. The VBR forwards traffic between your Virtual Private Cloud (VPC) and your on-premises data center (IDC). Only one VBR instance is allowed per shared port.
If you already have an existing cross-account VBR instance, after you complete Step 1: Accept a shared port, your existing VBR instance is automatically associated with the converted shared port. You do not need to create a new VBR instance.
Log on to the Express Connect console.
In the top navigation bar, select the target region.
On the Physical Connection page, click the ID of the target shared physical connection instance.
On the VBR tab, click Create VBR.
In the Create VBR panel, configure the following parameters and click OK.
Parameter
Description
Account
By default, Current Account is selected, which creates the VBR instance under your current account.
Name
Enter a name for the VBR instance.
Physical Connection Information
Select Hosted Connection and select the ID of the shared port instance. Make sure that the construction of the shared port is complete and its status is Active.
VLAN ID
Displays the VLAN ID specified by the partner. This value cannot be changed.
Alibaba Cloud-side IPv4 interconnect IP
Enter the IPv4 address of the gateway on the Alibaba Cloud side for routing traffic from your VPC to your on-premises data center.
client-side IPv4 interconnect IP
Enter the IPv4 address of the gateway in your on-premises data center for routing traffic from your on-premises data center to your VPC.
IPv4 subnet mask
The subnet mask for the Alibaba Cloud-side and client-side IPv4 addresses. A long subnet mask such as /30 is recommended because only two IP addresses are required for the point-to-point connection.
NoteAfter you create the VBR instance, you can modify its bandwidth, edit its properties, or delete it as needed. For more information, see Create and manage a VBR instance.

Terminate a shared port instance
Terminate a shared port instance to make it unavailable.
A terminated instance is not released. You can contact the partner to restore the instance to the Active state if needed.
You are still charged for a terminated instance. For more information, see resource usage fee. If you no longer need the shared port, you can unsubscribe from it to release the resource.
Log on to the Express Connect console.
In the top navigation bar, select the target region.
On the Physical Connection page, find the target shared port instance, and choose
> Terminate in the Actions column.In the dialog box that appears, click OK.
Delete a shared port
Before you delete a shared port, you must first delete its associated VBR instance.
Log on to the Express Connect console.
In the top navigation bar, select the target region.
On the Physical Connection page, find the target shared port instance and then click Delete in the Actions column.
If the instance has expired, click OK in the Confirm Deletion dialog box.
If the instance is still within its billing cycle, click OK in the Confirm Deletion dialog box. The system initiates a refund for the remaining balance and redirects you to the Unsubscription Center. For more information, see Unsubscription and refund.
